I'm not sure what your question is about. Exchange Online is using very similar technology to Exchange on premises, so uses those transport services. Messages get routed wherever you want them to go depending on the outgoing connectors configured. If none are configured they go directly to the internet. It is supported to use a 3rd party gateway if you like, you just need to configure the message routing and authentication correctly.
- The question : need reason Why i need to send email directory to internet without pass to 3rd party gateway
- You still get anti-spam and anti-malware as well as message authentication if you decide not to use a 3rd party gateway. The question you need to be asking is "What will a 3rd party gateway give me that I don't get natively with Exchange Online?" Once you have the answers to that question you can decide on the mail routing
